sheet when the impression. is made.

The

knife isshown in Fig- 4c comprisin a blade approximately crescent. shaped, .t e main portion emaking the registering ortion of the incision which is to engage t e gage in the embossing press and having two horns 6 e extending therefrom a; in obtuse an le as shown. I prefer'to set these knives in t e Inannershown, 1; imely, in such a way that two will be approximately upon. the line of separation of' the parts of the sheet and two parallel therewith upon the short side ar i two upon the longer margin of the sheet, but their arrangement wi ll depend upon the location of the gages upon the press upon which the) final impression is to be given. The

straightor register edges represented by thelines f, f (see Fig. 3), will engage the gages on the press and bearing always the same relathe waste 9 lying between the cut and each incisionwill fall out leavin the edge f exposed. It will also be seen t at this cat need not be absolutely accurate owing to the length of that part of the incision made by the horns e" of the knife'which allow for a slight inaccuracy in' 'the placing of the sheet i This with relation to the gu lotine knife.

' irregularity or variation may be as much as 3/16 or an inch, that is, asmuch as the distance of the straight edge of the knife blade is from the edge of the frame in which it is set. The kr fe blademay be of any cor.v venient sha e, so long as'the incision which it makes wil coo eratewith thecut of the guillotine. It is est made of a single blade set against a shank e against which it is.

clamped by a clamp e and screws e When the ends'or horns e e areat an angle to eachother they serve as guides toguide the registering portion of the in "ision towards its position against the gage in the press. 7

In using the term im ression in this s ecification and in the claims Imean to in-. c ude either the act of making an impression in ink which in color work after the first im-.

pression requires accurate registration where a second color 1s to be added, or such lmpression as will result in embossing a figure upon a sheet, or scoring, or die cutting. In using the term edge in reference to the reglstersashes ing portion of the sheet I mean to include any portion of the edge of the sheet, however minute; which may be exposed in the manner described and may serve with a gage properly shaped to. properly register the sheet.

' What I claim as my invention is:

V 1. The method above described of securing apsolute re istration of a sheet whereon a piuralityof esigns are rinted which consists in incisiors in t 1e sheet near the line of separation 'of one design from another,

each incision being shaped for the greater part of its length to engage a ga e of predetermined hape, the ends of eac incision projecting b yond thepredetcrmined line of separ' tion between the said design and the one adjacent to it, and then separating the said design from the one next it by a cut extending across the ends of said incision whereby the material between said incision and said out will be r moved and the edge of said incision will serve as a register to engage a gage as described. 7

2. The method abc re described of securing absolute registration of series of sheets which )IlSlS'LS in making incisions in each sheet at the'time of impressing a design thereon, each incision having a registering edge and. then trimmi the sheet whereby the registering edges wi 1 be exposed.

3. The method above described of securing absolute registration of a series of sheets which consists in making incisions in each sheet at the time of impressing designs thereon, then separating each sheet into sections by'a cut crossing each incision at two points whereby the waste exposed by said out will be so arated therefrom exposing the register gage ine.

4. The method above described of securing absolute registration of. a series of sheets which consists in making a series of crescentlike incisions therein simultaneously with the printing of designs thereon and then separating a p-urality of such sheets su erimposed into sections by a cut crossing t e horns of each incision as described.

5. The method above described of securing absolute registration of a series of sheets, which consists in making incisions in each 1 sheet at the time of impressing adesign e thereon, each incision being shaped to crossed at two pointsby a cut and then trim.- ming the sheet by a cut crossing such in cisions at two points, as set forth.
